I nodded in agreement as Sam suggested where to start measuring, following him. I put the end measuring "0" down right in front of the tree, setting a medium-sized stone on it to keep it from moving. Then I dragged out the long ribbon-like measuring tape to 100 metres and put it down. There weren't any stones around this grassy area, so I stood on it, already forgetting it belonged to someone else. Holding out the stopwatch, I nodded to Sam, calling, "Ready when you are!" In all my interest to see what he was about to do, I wasn't really thinking about morphing or getting any animal DNA.
